TRX420FM rough clutch engagement

I have a 2013 rancher 420 4×4 footshift atv which i thought was in pretty decent shape, i took over payments with very low, all pavement miles on it (got it from a family member) and ever since i got it, it has had a vibration in it in every gear at low RPMs. I thought it was just a break-in thing with the clutch and that it would go away eventually and just kind of got used to it. I have rode it ever since january nearly every day, and i am beginning to think that it is something malfunctioning in the clutch, not a break in thing. The manual says it could be a number of things, but i hate to tear into it blind. Anybody had this same problem/a solution?Attachment 24665
